So I love a 15" and like the punch of a 210

I don't want to lug around with a 210 and a 115 A few details:
- I play a peavey mark IV head, in our practise room I play that one over two 15" cabinets: good tone.
- I really love that 'boom' the 15" speakers always seem to give me.
- I like the way the 10" speakers growl, but I like the boom.
- I absolutely hated the ampeg 4x10 / 8x10 setups I played, so that makes me wonder: do I want a 210?

My question is:
is it possible to get that 'boom' out of an 210, so I would have a portable cabinet with punch and boom? I will be building my own cabinet with help of a professional speakerbuilding company and my dad (who has build speakers before).

The peavey puts out 300 watts @ 2 ohm and 200 @ 4 ohm.. What would be your advice in terms of a cabinet: 2 or 4 ohm? Is it possible to have the cabinet in 2 ohm when I use 10" speakers?

Anyone?

EDIT: oh and I live in the netherlands, so getting a schroeder will be too expensive etc etc.

the mark IV is a great head, but If you can find an old peavey 1810/1820 or 1516 I think it would work well for what your looking for the 1810 has one 18 and two 10's. while the 1516 has one 15 and two 8's. I have owned the 1810 and wished I had never sold it. you just cant get the same rumble with 12's as you can with 15/18's. but for an all around speaker I think the 212 or 412 is a great choice.

I see yor point. For the same reason I consider very seriously the DR280, a do-it-yourself cab on www.billfitzmaurice.com. It has a single 12" but the cab design is very different. It measures 60x60x60 cm and weighs about 30 kilos, but is more powerful than a 2x15 ......
